SYR'INGE.

SPECIFICATION forming part of Letters Patent No. 244,652, dated July 19, 1881.

r Application filed May 16, 1881. (Model) T spray of any required degree of fineness may be produced, and with less friction than usual. The invention consists of a nozzle with flarin g lip, containing several fixed cross-bars and adjustable basket-like devices and ataperin g screw-thimble, by whose adjustment relatively to each other and to the cross-bars the finenessof the spray issuing from the nozzle is regulated.

Figure 1 is a longitudinal sectional elevation of the device on line a: m, Fig. 2. Fig. 2

- is a plan of the reverse of the larger basketlike device. Fig. 3lis a side elevation of the smaller of the basket-like devices. Fig. 4 is a plan of the tapering screw-thimhle, holding the parts together. Fig. 5 is asectional elevation of a portion of the nozzle-shell and its contaiued parts.

Similar letters of reference indicate corresponding parts.

In the drawings, Arepresents the cylindrical nozzle-shell, secured on the end of a pipe, A, and provided with an outward-flarin g lip, a, at theinner edgeof which is an annular shoulder, b, beveled on its inner face, as shown at 0.

Bi gidl y secured within-the nozzle-shellAare four cross-bars, B, preferably of oval crosssection, from-whose central point ot'union a screw, 0, projects forward in the axis of the nozzleshell A to the plane of the outeredge of the top thereof, as shown in Fig. 1-. Over this screw 0 isfitted an adjustable basket-like device, D, consisting of an annular hub, d, from which several forward-projecting radial 'ribs or arms, f, project, supporting on their ends a flattened ring, 9, whose outer face is flush with the outerface of the annular shoulder b, and whose edges are beveled, as shown at h 1 Over and upon the screw 0, and within the basket-1ike device D, is fitted a smaller basketlike device, E, consisting of hub 7s and forward projecting arms I, supportinga flattened ring, m, whose outer edge is beveled, as shown at 'n, the face of said ring m being flushwith that of the ring g. These devices D E are held in position by means of a tapering screw-thimble, F, that is screwed on the screw 0 and within the device E, as shown in Fig. 1, with its face flush with the faces of the devices D E, and with its exterior tapering or beveled, as shown at 0.

It will be seen that with the'parts in position as shown in Fig. 1 concentric annular V- shaped openings are formed between the beveled faces I) i and ha, and annular openings also between the outer face, 0, of the screw-thirnble F and the inner face of the ring of the basketlike device E, through which openings thin annular sheets of water may be forced by the action of the piston G.

The devices D E are designed to be adjusted relatively to the cross-bars B and to each other in such a manner that the arms or ribs fl of the one shallbe,- if desired, opposite the inof the other and coincident with the intermediate spaces between the bars B, whereby the liquid issuing from thenozzleA shall be broken into fine spray.

It will. be seen that by having the basketlikc devices D E adjustable their arms or ribs f Z can be arranged in any desired relative position with each other and with the fixed bars B, so that the issuing jets of liquid may be more or less broken up, as may be desired, and by beveling the edges of the concentric rings 9 m the friction of the escaping fluid is much reduced.

In the drawings, Fig. 1, the nozzle-shell A, tube A, and piston G constitute a syringe, and when the piston Gris withdrawn or pulled out to draw water through the nozzle-shell A When the nozzle-shell A is used on a hose the part D will have no play, but will be held against the screw-shoulder and the part E, in proper relation thereto, by the thimble F.

I do not confine myself to two basket-like devices in the construction of the improved nozzle, as it is obvious that their number may be increased with advantage for certain purposes without departing from my invention.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent- 1. A hose-nozzle constructed substantially as herein shown and described, consisting of shell A, having flaring lip a, containing crossbars 13, screw 0, bevel-edged basket-like devices D E, and tapering screw-thimble F, arranged and operated as set forth.

2. In a hose-nozzle, the combination, with the nozzle-shell A, provided with outwardfiaring lip 60 and beveled annular shoulder 12, and cross-bars B, and screw 0, of the adjustable basket-like devices D E, provided with ribs or armsfl, respectively, supporting beveledged rings 9 m, respectively, andheldin place one within the other by beveled thimble F, substantially as herein shown and described, whereby the liquid issuing from the said nozzle is broken into spray, as set forth.

3. In a hose'nozzle, the combination of two or more basket-like devices provided with arm-supported bevel-edged rings, fixed adj ustably one within the other, substantially as herein shown and described, whereby annular jets of water and spray may be ejected, as set forth.

CHARLES OYSTON.
